Be it known that l. \l'iLLiAM J. Buaunrr.

citizen of the United States, residing atv lirooklyn. in the county ofKings and State of New York. have invented a certain new and usefulIn'iprovment in 'inding-Machines. of which the following is a. full,clear concise. and exact description.

This invention relates to automatic winding machines. such as are run bypower and arrange insulated wire in helical coils on bobbins,automatically stopping when a predetermined number of turns have beenwound.

The object of this invention to provide for stopping the Winding whenany number of turns have been wound and then if the electricalresistance is not at a fixed point (owing to variation in the wire),automatically winding the required additional number of turns, stoppingautomatically: and further. to provide automatic means where by thestart to wind is at the end of a bobbin instead of at an intermediatepoint where the stop may have been made to secure the required number ofturns and amount of resistance, and combining with this means a handoperated device to throw the last named means in and out of operation,as with a single simple movement.

The accompanying drawings illustrate the invention.

Figure 1 is a top plan View with part of the main shaft broken away;Fig. 2 is a rear elevation partly in section showing the means wherebythe start is automatically made at one end or the other of the bobbin;Fig. 3 is a broken section showing the cam for reciprocating the wireguide, and the means for determining the number of layers wound; Fig. 4showsthe connection between the cam and the gradually advancing trippingdevice: Figs. 3, 6 and 7 are sectional views of details of construetion. and Fig. 8 is a perspective view clearly illustrating the relationof the parts in operation.

lhe bobbin or core to be wound with wire is placed between the drivenhead block a. and the tail block 7) both located on a suit-- able bedplate, and said core or bobbin is Specification of Letters Patent.

clutched in any suitable manner. Wire is supplied from an overhead reelsupl'iorted on a rod (not shown) located in s cket c. Tle head a isdriven by an electric motor connected on shaft m. which motor is conl'ltlllGtl by a starting switch and resistance fit) in manner wellknown. Shaft. m is connected to shaft 21 by gearing 1, and shaft 11 isconnected by worm gear (not shown) to transverse shaft 22 on which isfixed cam Cam A: engages rollers 23 and .24 en a reciprocating carriage0 supporting the wire guide 200. which guides the wire so that it liesclosely in successhe helical turns, in layers. on the bobbin 203. Thecam A. re verses the ll'lOVtllTltllt of this guide. at each end of itstrip from one ide to the other; cam 7r turns continuously in onedirection and. as shown in Fig. t. has carried the guide to its extremerighthand limit.

A tension device, like that shown and described in United States LettersPatent No. $90.24 dated June 9. tool issued upon the appl' *ation of F.ll. lloveridge, employed: and a device to compensate for the increasingdiameter of the bobbin to be wound is employed which ditl'ers in somerespects from that shown in said Loveridgo patent. After leaving saidtension device the wire passes to the wire guide ".200. a companionroller 20 prevents displacement of the wire from the grooy ed peripheryof the guide 200; the guide 300 is rotatably supported at 201. on alever 2UP; pivoted at '20 on a standard 207. The upper end of standard207. is bifurcatc-tl and carries a cam wheel 208. on a short shaft 20ftin bearings in the standard 207. so that the shaft is free to rotate: onthe end of shaft 209 is a disk with a milled periphery 210 for handmanipulation. .\n arm Ell is pivoted on standard 207 and its free outerend is forced downward by a spring 21:). rd 213 has one end fast on theend of lever 211; it is turned around shaft 201 and its opposite end isfast to said shaft: the arrangement being su h that shaft 20!) and cam208 have a tcl'idcncy to rotate it) ward the rear side of the machine.but this tendency to rotate is held in check by a brake 214 engaging theperiphery of the cam sure of the wire guide 2 .10 on t f the bobbin 205.

To determine the number of, layers to be wound before the desiredautomatic, stop occurs, there a did-130 loose on shaft or hearing theperiphery of disk is toothed and it is held by a stop 31 'adjustablyfixed on standard disk 30 carries a resilient stop and disk 30 isgraduated and can be rotated and set to indicate the required number ofto and fro excursions of the wire guide as will be now described. Onshaft 25 ratchet wheel 33 is free to rotate; wheel 33' carries a rollerstop 34; a spiral spring in connects wheel 33 to shaft 25; the spring a(Fig. 2) is in a box y and returns wheel 33 to its starting positionwhen it .is released, after being stepped ahead to the tripping oint.When wheel 33 is at its starting point the roller 34 on its surfaceengages spring stop 35 on the surface of disk 30. The ratchet wheel 33is advanced st p by step by a pawl 36 pivoted at. 37 on the oscillatinglever 38; a sp l\! ovl 3G in engagement with while holding pawl 40,retains wheel 3 during Q0 tin e pawl 36 is on its return movemen l.

The oscillating lever 38 is journaled on the short shaft 25,and itslower end is bifurcated. There is a roller 41 on a two-part disk 42, 43,on shaft 22 held in fixed but adjustable position by a ring or coTlar 45and a set screw 46; the roller 41 is between the bifurcations of lever38 and as shaft 22 rotates, roller 41 engages first one leg of lever 38and then the other, this advances and withdraws pawl 36 which thusadvances ratchet wheel 33, one tooth for each rotation of shaft 22. oreach complete rotation of cam is, or each complete excursion of the wireguide; so that two layers are wound for the advance of each tooth orspace on the periphery of wheel '33. The starting lever is shown at h,pivoted on shaft 2 and in Fig. 8 is shown retracted by spring 47. iVhenmoved forward, or to the left Fig. 3, or away from the operator, aprojection 101 on lever it passes out from under projection 48 on pawl36 and a stop 50 onlever it passes from under projection 51 on pawl 40,so that said pawls drop into engagement with wheel 33; when retracted,or moved to the right Fig. 3, lever it, raises pawls 36 and -10; so thatin its forward position starting lever ]L releases pawls 36 and 40 andthey engage t hlpivoted at t V d forward by spring 61. tarting ievcr /'ilrw a curved '()Illt1(t edge 4?), Fig. 33, which i. notched or slotted,as shown in l J. 2 and and plate or lever has a projecting hardenedsteel contact-tooth. beveled on its free or contact edge, adjustablysecured by a screw. This tooth rides on the curved periphery of leverplate it and enters the notch in lever plate It as said lever is movedforward to start the machine into operation. in inclined edge 63, (Fig.2), of lever 60, takes a position in the path of roller 351 on ratchetwheel 33; this roller presses lever 60 to the left (Fig. 2) and releasesstarting lever h which in turn lifts pawls 36 and 40 described so thatwheel 33 returns to its starting point, with stop 34 engaging stop 35. Aprojection 64 on starting lever It strikes motor-switch holding-catch 65(Fig. 1) opens the circuit and the machine stops.

The machinery so far described provides for setting the stop mechanismto automatically trip at the end of any number of com plete layers, andat an intermediate point in a layer; this is done by setting the disk 30to automatically stop at the end of a layer and the roller 41 to producesuch stop at an intermediate point in a layer. This invention providesan ilnproved means for setting the stop mechanism at an intermediatepoint in any layerby changing the position of the roller 41 afterloosening the screw 16 (Fig. 3) on the ring 45 which clamps the two halfdisks 42 and 43; a graduated scale 150 being used to determine theposition of the parts 42 and 43. This novel invention further providesmeans to automatically start the winding operation every time at theinitial end of the bobbin, or at either end, 'as may be determined uponwithout regard to Where it may have been stopped intermediately; and todo this without manipulating the driving apparatus or the adjustingdevices held by set screws as described; audit is combined with a simpledevice by which said means for automatically stopping at an end may bethrown in and out, of operation by a single movement.

As before stated lever (30 is pivoted at 62, it catches and holds thestarting lever 11 in its forward or running position; lever 60 istripped when roller 34, on wheel 33, strikes incline 63. Means areprovided to trip lever 60 by the movement of the reciprocating two-partcarriage 0, 0, which carries the rail If and on which is located carrieror standard 207 supporting an arm 83 extending forthreaded end Ward, andupon which there is a slide 82 (Fig. 6). There is a fixed post 87 (Figs.1

and 7) supporting pivoted lever 84; one end of lever 84 enters aperforation 85 in lever 60 (Fig. 4). A horizontally disposed rod 10(Fig. 1) is pivoted to lever 84 at 86; there is a parallel rod '0jointed at90- to a short section 89 (Fig. 2) pivotally supported at 88in a post 91 (Fig. 1) supported upon the tail block. The lower terminalof section 89 is bifurcated and straddles the screw of rod 10; on thescrew threaded end of rod to are limiting nuts 92 and 93 and there is acheck nut for each. The rods '0 and w are mutually supported by a stop95, fixed on rod w through which there is a perforation in which rod 1)passes; there is a stop 94 fast on rod 1;. By pushing slide 82 up sothat it is in position to engage nut 92 when carriage 0 is moving towardthe tail block 6, rod 'w is moved and through link 84 it moves lever 60.This automatically stops the machine at the limit of the windingoperation. Byplacing slide 82 on the'tail block side of stop 94 itsupper edge strikes stop 94 on rod 4) and moves rod 11 to the right androd w to the left or toward the block b, and lever 60 is tripped asbefore, but in this case it is tripped when" the wire guide is at theopposite end of the bobbin or the opposite end of'its movement. Slide 82is now withdrawn. By changing the position of stop nut 92 or theposition of stop 94, the winding may be automatically stopped at eitherend of the bobbin by advancing slide 82 and the automatic devicedescribed is quickly thrown inand out by a single movement of the slide82 which is located at the front center of the machine and is easily andquickly moved.

In operation a blank spool is inserted between the holding devices a and6, starting lever h is moved forward, and the machine starts. Theresistance of the wire'is such that it is necessary to stop the windingop- I eration when twenty and one-half layers of helical convolutionshave been wound onthe spool. This has been provided for by looseningscrew 46, Fig. 3, and moving the two-part disk 42, 43, with the contactroller 41 to the predetermined point on the scale 150 so that staringlever 72, will be tripped at that point. When the machine is thusautomatically stopped the wound spool is withdrawn. It-"is necessary tobegin the winding for the next spool at one end to have the windingterminate at the half layer, the same as in the case of the spool firstwound. We must therefore start at the end. The winding guide isautomatically moved to this initial point each and every time by moy-ingup the slide 82 by hand when the first-spool is removed and a secondspool in serted, then throwing lever h forward-this starts the machineand it isautoniatically stopped at the initial end of the blank spool,the end of the wire is then brought into en gagement with the blankspool,the machine is started again and again automatically stopped at ahalf way point when twenty and one-half layers are wound.

This improved device provides a manually operated means for quicklythrowing into action an automatic device for complet ing the excursionof the wire guide over the fractional art of a layer and automaticallystopping t 1e wire guide at the same initial point, so that the Windingmay always start at the 'same terminal point.
